I've been trying to figure out how to upload a file to my new inReach Explorer + when I'm not online. As far as I can tell, and as I've been informed by support over the phone, this is not possible. The only way to upload a file of routes or waypoints is by:
1. Uploading routes or waypoints to the online mapping tool inreach.garmin.com
2. Synching the online maps using InReach Sync
While this approach might work in the office it is completely unsuitable off grid. What ever happened to plugging in a USB cable and dropping whatever you wanted on your device? Why has usability gone back decades? Am I really expected to manually enter waypoints? What a dangerous waste of time.
Pretty disappointed and would love to be corrected.
